Apple has recently seeded the iOS 5.1 beta to developers with new features, and as well with new security measurements to the core of iOS 5.x well for those who still wish to go with iOS 5.1, after getting a strict warning from iPhone DevTeam for not to update your iOS to any update until they do not find any new exploit. However, if you still want to download, you can download the latest beta from Apple’s Developer Portal. As reported by the famous hacker iH8sn0w, the latest beta will be expired on January 14th, 2012 at 8PM EST.
This means if you are updating to iOS 5.1 first beta and does not update your device to newer or final version of iOS 5.1 before the expiry date, your device will be broken, and you will not be able to use it anymore. Well, we can expect that Apple will shortly roll out its newer beta version or complete version.
